There is a marginal chance for severe weather this evening across
southeastern South Dakota and parts of southwest Minnesota. Hail

flooding.
Some severe weather is possible Saturday and Sunday. However, location
of the severe weather threat both Saturday and Sunday remains
difficult to determine, dependent on exactly where the front sets
up.
